Be it known that I, MALooLwr G. MAJOR, a citizen of the United States,residing at Washington, District of'Columbia, have in vented certain newand useful Improvements in LetterSheets, of which the following is aspecification. I

This invention relates to letter sheets, and has for its object toprovide a device of this character particularly adapted for use in'connection with advertising matter, which 1 advertising matter may bedisplayed within thesheet, and then the" sheet folded into a compactpackage, and held-folded sothat the same maybe mailed.

invention is to provide the sheet with detach addressee forinformation,or as a co' upon for "special premiums.

A further ob ect is to provide aletter sheet substantially square, saidsheet being provided with detachable triangular-shaped coupons at theoppositecorners thereof? and a plurality of parallel 'on' whichthevarious parts fold, said lines being interposed between-thedetachable coupons and in parallel relation to theadja- :ce'ntsides'thereoff thereby forming spaces for displayingpurposes. Theinvention fur- "-ther consists 1n*the provision of a letter sheet havingvertically disposed lines at --"1'ight-angles 'to parallel-lines, andextending -"fro'm the cornersof thetriangularly-shaped "coupons andforming lines on which the out.- war'dly extending opposite triangularporsheet may be folded inwardly during the folding operation of thesheet.

A further object is to provide one of the I triangular "shapeddetachable coupons 'with "mea-ns whereby the "coupon 'end may; be received and locked in a slot located centrally of the sheet for holdingthe'shee't in folded 1 condition, which-means may include a'notchdisgosed in an edge of the coupon.

still'further and particular ob' ect of the inv'entionfis to *prOVidea'letter sheet 'f01dable 'in" such Inanner as 'to have the appearanceofan envelop, and wherein thesec'uring thereof-"may be sealedorpermanently attached to 'the body of" the sheet," and yet theinner'portionsor surfaces of thesheet flap, or 'tearlnganypart'of the" sheet.By

disposed scored linesreadily viewed orinspected without unfolding" thesheet, 'breaking 'the sealed;

this particular method of folding and sealing the sheet, the same may bemailed other than as first class mail matter.

lVith the above andother objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth,- shown inthe drawings, described and claimed, it being understoodthat changes inthe precise embodiment ofthe invention may be made 'w'ithin'the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawings:

Figure 1 is a plan View of the outside of the letter sheet showingthe-same in open condition, I ablecoupons which maybe returned by theFigure 2 is a perspective view of the sheet showing the inside thereofand the sheet ready to be folded,

Flgurefi is a. perspective showing'the let ter sheet folded.

Figures l and 5 show initialsteps, after the corner members have beenfolded inwardly, in folding the blank into envelop form,

Figures-6 and? show'the next successive steps 1n folding the panels ofthe blank, and Figure 8 is. a view'showi'ng the folding completed allbut folding the securing flap and securing the "sameto'the back of thecentral panel.

Referring; to=the drawingsjthe numeral 1 designates a rectangular shapedpiece of paper preferablysquare," which" rectangular shaped piece. ofpaper on itsout'sid'e is provided with lines 2 vertically? disposed andinparallel relation to each other, each of said lines beingequallydistant from a center line drawn between the opposite corners 3of the sheet 1, saidlinfes Qbeingintersected by spaced lines 4: equallydistant on each side of the'linedrawn between the corners 5 of the sheet1.; It will be -s'een that oblong shaped sections or panels'6, 7 and 8are formed by the "lines 2"and' 4 and .by the scored lines 9,'which formthe t'ria'i'igular shaped detachable coupon sections or' flaps 1O, andon the inside faces of thesections 6, 7 and 8 various advertising mattermay be disposed or p-i'ctorial views ,if des'ired. The outside ofthesection'6is*ipr0 videdwith a space 11 for a stamp and a plurality oflines for the name and address of "the addressee. The section 7' at apoint substantially centrally thereof is provided with a slot 13,

which slot when the device is folded as shown in Figure 3 receives thepoint 14 of one of the detachable flaps or coupons 10, and forms meanswhereby the letter sheet may be maintained in folded position. If sodesired the point 14 of the coupon lO may be provided with a coating ofgum 15 whereby the sheet may be sealed in closed position. hen theadhesive is used to secure the coupon, the point 14 will not be insertedin slit 13, but will be adhered to the outer face of the panel 7, aswill be obvious.

By providing the coupons, return addresses may be-obtained, or specialoffers made upon presentation of one of the coupons used for otheradvertising purposes. W hen it is desired to fold the sheet thetriangular shaped corner portions 16 are folded inwardly on the lines 2as clearly shown in Figure 2, said portions 16 being folded inwardlyonto the inner faces of the sections 6, 7 and 8. After the portions16have been folded inwardly the lower coupon section 10 is either foldedunder, as shown in Figs.

5 and 7, or inwardly, as shown in Figs; 4:

and 6, and the section 8 folded upwardly on thelower scored line 4: andthen on the next scored line 4. This will bring the outer side of thesection 7 outwardly and allow the securing point 1 1 to be inserted inthe slot 13 for securing the sheet in folded position.

Bv folding the sheet in this manner, the inner portions or surfaces ofthe folded sheet may be viewed or inspected without detaching, breakingor deranging the securing flap, and without i juring any other part ofthe sheet. This inspection is accomplished by exerting slight pressureupon the longitudi-.

nal edges of the folded sheet toward each other, whereupon the envelopwill be bowed so as to expose certain of the folded inner portions,panels or coupons. Those inner portions not visible by this operationmay be brought to view by being partly withdrawn fromthe packet orenvelop;

withdrawn from the envelop a'slight twisting action upon such portionsbeing helpful in the attainment of this end. As this twisting movementis exerted only upon the innermost folded portions of the sheet, and asnone of these parts are interlocked with each other, no damaging strainwill be imparted to the securing flap or outer portions of the foldedsheet. The parts in this manner may be easily and quickly returned totheir proper folded positions by a reverse twisting movement, and theenvelop at once assumes its original folded form and appearance.

From the above it will be seen that a letter sheet is provided. which isparticularly adapted for advertising purposes or for pictures, forinstance views of a city. It will also be seen that the sheet is simplymade and the interior thereof is so divided as to folds and sectionsthat its entire surface may be utilized for advertising purposes. Itwill also be seen that detachable triangular shaped coupons are providedfor return purposes and that one of said coupons forms securing meansfor holding the sheet in folded position.

The invention having been. set forth what is claimed as new and usefulis: i

1. A foldable letter sheet comprising a square sheet of paper, aplurality of scored lines on said sheet, disposed horizontally and atforty-five degrees to the side of the sheet, a plurality of linesvertically disposed at forty-five degrees to the side ofthe sheet andintersecting the horizontally disposed lines at righ angles,horizontally disposed perforated lines connecting the upper ends of thevertically disposed scored lines thereby forming triangular shapeddetachable coupons, a horizontally disposed slot located substantiallycentrally of the sheet, and means whereby one of said coupons when thesheet is folded upon itself will be received and held in said centrallydisposed slot.

2. A foldable letter sheet comprising a square sheet of material, saidmaterial 'being provided with pairs of vertically and horizontallydisposed spaced parallel lines, the lines of each pair being disposed atequal distances fronrlines drawn between the corners of the sheet,horizontally disposed perforated lines connecting the ends of thevertically disposed lines thereby forming detachable triangular shapedcoupons and means whereby one of the corners of one of the coupons, whenthe sheet is folded, may be secured to the centrally disposed section ofthe sheet formed by the scored lines.

3. A letter sheet comprising a square blank having central, upper andlower panel sections of the same dimensions, coupon sections at thetopand bottom respectively of the upper and lower sections, corner portionsflanking the central, upper and lower sections, and the said centralsection hav ing a slit disposed centrally thereof and parallel with theadjoining edges of the central and upper and lower sections.

4. A letter sheet comprising a blank having panels, corner members andflaps, so folded as to enable one of the flaps to be permanently securedto apart of said sheet and permitting all portions of the sheet to beviewed by being partially withdrawn from the folded pack or envelop andreturned thereto without unfolding the same or detaching or breakingsaid secured portion.

5. A letter sheet comprising a blank having a series of parallel panelsfoldable upon each other, corner members flanking said panels, andcoupons on the outer edges of folding the end panels; the blank adaptedto be folded by first folding the corner members inwardly upon the innerfaces of the panels, the coupon of one end panel upon the latter, thenfolding the panels upon each other successively from one end to theother of the blank, passing the coupon of the last folded panel overupon a reverse surface of the next adjacent panel, and securing saidcoupon to the said panel.

6. A letter sheet comprising a blank having central, upper and lowerpanels arranged in parallel relation, flaps at the outer edges of theupper and lower panels respectively, corner members flanking saidcentral, upper and lower panels; the said blank adapted to be folded bybending said corner flaps inwardly upon the faces of said panels,bending the flap of the lower panel upon the panel to whichit isattached, then folding the panels successively upon each other from thelower to the upper end of the blank, passing the flap of the upper panelover upon the reverse side of the central panel. and securing said flapto said panel.

7. A letter sheet comprising a blank having a series of panels disposedinwardly from the top, bottom and sides of the sheet, flaps at the outerextremities of the end panels of said series, corner portions flankingsaid series of panels; the said blank adapted to be folded by bendingthe said corner portions inwardly upon said series of panels at theirjuncture with the latter, folding one of said flaps back'wardly upon itsadjacent panel at the line of juncture thereof, then folding the saidpanel and flap inwardly upon the next adjacent panel,

then folding the remaining panel over upon the parts thus folded andextending the other flap over the folded, panels and securing the sameto the panel lying directly under the same.

In testimony whereof I'hereby affix my signature.

MALCOLM Gr. MAJOR.
